DEVICE FOR MANUFACTURING PAPER SHOT-SHELLS.

SPECIFICATION forming part of Letters Patent No. 237,701, dated February15, 1881.

Application filed July '7, 1880. (No model.)

To all whom it may concern:

Be it known that we, CAESAR A. RODNEY and J OHN M. O. RODNEY, both ofWilmington, in the county of New Castle and State of Delaware, haveinvented a certain new and useful Improvement in Apparatus forManufacturing Paper Shot-Shells, of which the following is aspecification.

Our invention relates to machines for manufacturing papercartridge-shells composed of a tube of paper, a metallic head, and apaper wad or base, more especially to such as are shown in Patent No.125,508, granted to O. S. Wells, April 9, 1872, and in an applicationfor Letters Patent filed by us on the 19th of April, 1879; but it isalso applicable to machines in which the punch or header enters the dieand upsets the flange on the shell.

in our application above referred to an apparatus for making papercartridge-shells is shown,whichis capable of producing uniformlyperfectshells irrespective of ordinary variations in the bulk of the paper Wadand in the thickness of the paper tube.

In machines in which the punch enters the die it is necessary to havethe paper wad of a uniform bulk, as any excess will cause the metalflange to fin or flow between the punch and walls of the die.

In practice it is impossible to have the wads and tube of a uniformbulk, and therefore much had work is produced and considerable waste ofmaterial caused.

The object ofour invention is to providefor this variation in material,and to produce uniformly-perfect shells irrespective of suchirregularities in the bulk of the wad and tube as would ever occur inpractice.

Our invention consists in providing an elastic support for the pin ormandrel on which the cartridge is compressed, so that when a certainamount of pressure has been reached the mandrel will yield, and thusprevent the flange of the shell from finning.

The accompanying drawing is a central sectional view of a cartridge-diesuch as shown in our above-mentioned application, showing part of thedial and bed-plate of a cartridgepress and the yielding support for themandrel.

In the construction shown in the drawings a series of dies, A, will bearranged in the re- I flange a.

snugly in this opening, so as to be capable of moving freely up and downtherein, and has upon its lower end a nut,f, by which itcan be adjustedso that its upper end will be flush with the surface of the bed-plate.This head or bolt is supported by bar or plate springs G, of therequisite strength, mounted upon bolts H depending from the bed-plate.By means of nuts h upon the bolts H the upward pressure of the springsupon the supporting-head can be regulated as may he desired.

The die shown in the drawing is supported by a spring, a, so as to yieldas the header descends, its upward rise being limited bythe It isobvious, however, as before stated, that our invention is equallyapplicable to non-yielding or stationary dies which are entered by thepunch.

As the dial of the press pauses under the header the mandrel will restsolely upon the supporting-head. The header then descends and compressesthe cartridge. The mandrel will yieldonly when the compression of thewad between it and the header exceeds the strength of the spring whichsupports the head or bolt upon which it rests. This spring musttherefore be of sufficient strength to insure the proper compression ofthe wad and its requisite lateral expansion to fill the flange of theshell, conform it to the recess in the die, and solidly compact the wadtherein. It will be obvious that the force of this spring can be soregulated that the flanges of the shells will never fin or flow, andthat at the same time strong compact cartridge-shells having bases ofequal solidity can uniformly be produced.

A further advantage of our invention is that as the mandrel will yieldthe crank of the press will be relieved from the strain which would becaused by an unusually large wad.'

Again, where the pin is stationary and an extra large wad is used thetube is liableto be cut off by the pressure at the edge of the brass.

This objection is obviated by the use of the yielding mandrel.

Instead of having one spring beneath the header of the press, it mightbe desirable to place a spring beneath each mandrel in the dial, so thatthe whole apparatus would revolve upon the bed-plate.

It will be obvious that the details of construction herein described maybe varied without departingfrom the spirit of our invention.

Having thus described our invention, what We claim as new, and desire tosecure by Let- "ter's Patent, is--' 1. The combination of a cartridgeheader or punch, a yielding or non-yielding die, and a yielding pin ormandrel, substantially as set forth.

2. The combination, substantially as hereinbefore set forth, of thebed-plate, the die, the pin or mandrel, the supporting head or bolt, andthe springwhich supports the head or bolt.

3. The combination, substantially as hereinbefore set forth, of thepunch or header, the revolving dial, a series of dies having loosemandrels thereon in said dial, the bed-plate upon which the dialrevolves, the mandrel-supporting head or bolt, and the spring whichsupports said head or bolt.

4. The combination of the bed-plate, the mandrel-supporting head orbolt, the adjusting-nut upon its lower end, the spring which supportssaid head or bolt, the bolts which support the spring, and the nuts foradjusting it, for the purpose setfforth.

In testimony whereof we have hereunto subscribed our names.
